repeating the tune constandly

hallo, I wan't to juse musescore for practising with my concertina. I can put the music on but I wish the tune starded over and over again so a can practisch with my instrument. When I always have to click on the startbutton I always lose a few barrs.I really wan"t to work with this site, there are others but they use ABC code and I'm not jused to it. They makes some suggestions like Audacity but I like this site. sorry for my Englisch. Greatings
